相對於往正方向被進給之線材W之進給方向而言，在線材進給部3A之上游側設有第1線材導引器4A1，在下游側設有第2線材導引器4A2，藉此，兩條線材W在並列之狀態下被進給。 With respect to the feeding direction of the wire W that is fed in the positive direction, a first wire guide 4A 1 is provided on the upstream side of the wire feeding portion 3A, and a second wire guide 4A is provided on the downstream side 2. By this, the two wires W are fed in a parallel state.

當線材W往正方向被進給時，線材W係通過固定握持構件70C與第2可動握持構件70R之間，通過捲曲導引部5A的第1導引器50的導引凹槽52。藉此，線材W係藉被第2線材導引器4A2導引(支撐)，與第1導引器50的第1導引銷53a及第2導引銷53b之兩點，被賦予捲繞到鋼筋S周圍之捲曲習性。 When the wire W is fed in the positive direction, the wire W passes between the fixed holding member 70C and the second movable holding member 70R, and passes through the guide groove 52 of the first guide 50 of the crimping guide portion 5A. . Whereby, by the second guide pin 53b of the second two wire guiding introducer. 4A 2 (support), and the first guide pin 50 of the first guide 53a of the wire W-based, is given volume The curling habit of winding around the steel bar S.

自第1導引器50被送出之線材W，係藉第2導引器51，被誘導到固定握持構件70C與第1可動握持構件70L之間。而且，當線材W的尖端被進給到對接於長度限制部74之位置時，進給馬達33之驅動被停止。藉此，如第11(a)圖所示，線材W係成環體狀地捲繞到鋼筋S周圍。 The wire W sent from the first guide 50 is guided by the second guide 51 between the fixed holding member 70C and the first movable holding member 70L. Furthermore, when the tip of the wire W is fed to a position abutting the length restriction portion 74, the driving of the feeding motor 33 is stopped. Thereby, as shown in FIG. 11(a), the wire W is wound around the reinforcing steel S in a loop shape.

在停止線材W之進給後，馬達80係往正轉方向被驅動，藉此，馬達80使可動構件83往做為前方向之箭頭F方向移動。亦即，可動構件83係與馬達80之旋轉連動之旋轉動作，被旋轉限制構件84限制，而馬達80之旋轉被轉換成直線移動。藉此，可動構件83往前方向移動。 After stopping the feeding of the wire W, the motor 80 is driven in the forward rotation direction, whereby the motor 80 moves the movable member 83 in the direction of the arrow F which is the forward direction. That is, the movable member 83 is a rotating motion linked with the rotation of the motor 80, and is restricted by the rotation restricting member 84, and the rotation of the motor 80 is converted into linear movement. Thereby, the movable member 83 moves forward.

彎曲部71係與可動構件83往前方向移動之動作連動，與可動構件83成一體地不旋轉，而往前方向移動。當 彎曲部71往前方向移動時，如第9(b)圖所示，開閉銷71a通過開閉導引孔77的開閉部78。 The bending portion 71 is linked to the movement of the movable member 83 in the forward direction, and moves in the forward direction without rotating integrally with the movable member 83. when When the bending portion 71 moves in the forward direction, as shown in FIG. 9(b), the opening/closing pin 71a passes through the opening/closing portion 78 of the opening/closing guide hole 77.

藉此，第1可動握持構件70L係藉將軸76當作支點之旋轉動作，往接近固定握持構件70C之方向移動。因此，在第1可動握持構件70L與固定握持構件70C之間，線材W一邊的端部WS側被握持。又，第2可動握持構件70R係藉將軸76當作支點之旋轉動作，往接近固定握持構件70C之方向移動。因此，於在第2可動握持構件70R與固定握持構件70C之間通過有線材W之部位，形成有可進給線材W之間隔。 Thereby, the first movable holding member 70L moves in a direction approaching the fixed holding member 70C by rotating the shaft 76 as a fulcrum. Therefore, between the first movable gripping member 70L and the fixed gripping member 70C, the end WS side of the wire W is gripped. In addition, the second movable gripping member 70R moves in a direction approaching the fixed gripping member 70C by rotating the shaft 76 as a fulcrum. Therefore, at a portion where the wire W passes between the second movable holding member 70R and the fixed holding member 70C, a space where the wire W can be fed is formed.

而且，當可動構件83往前方向移動時，可動構件83之動作被傳遞到後退機構53，第1導引銷53a係後退。 Furthermore, when the movable member 83 moves in the forward direction, the movement of the movable member 83 is transmitted to the retreat mechanism 53, and the first guide pin 53a is retreated.

藉第1可動握持構件70L及第2可動握持構件70R之開閉動作，前進可動構件83至握持線材W之位置為止後，暫時停止馬達80之旋轉，往逆轉方向驅動進給馬達33。藉此，第1進給齒輪30L逆轉，同時第2進給齒輪30R跟隨第1進給齒輪30L以逆轉。 By the opening and closing actions of the first movable holding member 70L and the second movable holding member 70R, the movable member 83 is advanced to the position where the wire W is held, and the rotation of the motor 80 is temporarily stopped, and the feed motor 33 is driven in the reverse direction. Thereby, the first feed gear 30L rotates in the reverse direction, and the second feed gear 30R follows the first feed gear 30L to rotate in the reverse direction.

因此，被夾持於第1進給齒輪30L與第2進給齒輪30R間之線材W，係往反方向被進給。藉使線材W往反方向進給之動作，如第11圖(b)所示，線材W係被捲繞使得密著於鋼筋S上。 Therefore, the wire W clamped between the first feed gear 30L and the second feed gear 30R is fed in the opposite direction. Due to the action of feeding the wire W in the opposite direction, as shown in Fig. 11(b), the wire W is wound so as to be closely attached to the reinforcing steel S.

在捲繞線材W到鋼筋S上，以停止進給馬達33逆轉方向之驅動後，往正轉方向驅動馬達80，藉此，使可動構件83往前方向移動。可動構件83往前方向移動之動作，係藉傳遞機構62A被傳遞到切斷部6A，藉此，可動刃部61A旋轉， 藉第2可動握持構件70R與固定握持構件70C，被握持之線材W另一邊的端部WE側，係藉固定刃部60A與可動刃部61A之動作而被切斷。 After winding the wire W onto the steel bar S to stop the driving of the feed motor 33 in the reverse direction, the motor 80 is driven in the forward direction, thereby moving the movable member 83 in the forward direction. The movement of the movable member 83 in the forward direction is transmitted to the cutting portion 6A by the transmission mechanism 62A, whereby the movable blade portion 61A rotates, By the second movable holding member 70R and the fixed holding member 70C, the end WE side of the other side of the held wire W is cut by the actions of the fixed blade 60A and the movable blade 61A.

如本例所示，當以兩條線材W捆束鋼筋S時，其與如習知之以一條線材捆束鋼筋S之情形相比較下，即使各線材W之直徑較細，也可獲得與先前同等之捆束強度。因此，可很容易彎曲線材W，以較小之力量使線材W密著在鋼筋S上。因此，可藉較小之力量捲繞線材W到鋼筋S上。伴隨於此，藉鋼筋捆束機1A之各馬達之小型化與機構部位之小型化，可使本體部整體小型化。又，藉馬達之小型化及減少負載，可減少消耗電力。 As shown in this example, when the steel bar S is bundled with two wires W, compared with the conventional case where the steel bar S is bundled with one wire, even if the diameter of each wire W is smaller, it can be compared with the previous The same bundle strength. Therefore, the wire W can be easily bent, and the wire W can be closely adhered to the steel bar S with a small force. Therefore, the wire W can be wound onto the steel bar S with a relatively small force. Along with this, the miniaturization of each motor of the reinforcing bar binding machine 1A and the miniaturization of the mechanism parts can reduce the overall size of the main body. Also, by miniaturizing the motor and reducing the load, power consumption can be reduced.

在切斷線材W後，使可動構件83更往前方向移動，藉此，如第11(c)圖所示，彎曲部71係與可動構件83成一體，而往前方向移動。彎曲部71係往做為箭頭F所示之前方向之接近鋼筋S之方向移動，藉此，使固定握持構件70C與第1可動握持構件70L所握持之線材W一邊的端部WS側，藉彎曲部71b1而往鋼筋S側按壓，以將握持位置當作支點而往鋼筋S側彎曲。彎曲部71更往前方向移動，藉此，在第1可動握持構件70L與固定握持構件70C之間，線材W一邊的端部WS側，係在被握持之狀態下被保持。 After the wire W is cut, the movable member 83 is moved further forward, whereby as shown in FIG. 11(c), the bending portion 71 is integrated with the movable member 83 to move forward. The bent portion 71 moves in the direction close to the steel bar S as the previous direction indicated by the arrow F, thereby making the end WS side of the wire W held by the fixed holding member 70C and the first movable holding member 70L , The bending part 71b1 is used to press to the side of the steel bar S to bend to the side of the steel bar S with the holding position as a fulcrum. The bending portion 71 moves further forward, whereby the end WS side of the wire W between the first movable holding member 70L and the fixed holding member 70C is held in a held state.

又，彎曲部71係藉由往做為箭頭F所示之前方向之接近鋼筋S之方向移動，使被固定握持構件70C與第2可動握持構件70R握持之線材W另一邊的端部WE側，藉彎曲部71b2而往鋼筋S側按壓，以將握持位置當作支點而往鋼筋S 側彎曲。彎曲部71更往前方向移動，藉此，在第2可動握持構件70R與固定握持構件70C之間，線材W一邊的端部WE側係被支撐。 In addition, the bending portion 71 moves in a direction close to the steel bar S as the previous direction indicated by the arrow F, so that the other end of the wire W held by the fixed holding member 70C and the second movable holding member 70R On the WE side, press the bending part 71b2 to the side of the steel bar S to use the holding position as a fulcrum to move to the steel bar S Side bending. The bending portion 71 moves further forward, whereby the end WE side of the wire W is supported between the second movable holding member 70R and the fixed holding member 70C.

使線材W的端部往鋼筋S側彎曲後，馬達80更往正轉方向被驅動，藉此，馬達80係使可動構件83更往做為前方向之箭頭F方向移動。可動構件83移動至箭頭F方向之既定位置為止，藉此，可動構件83係自旋轉限制構件84之卡止抽出，可動構件83之由旋轉限制構件84所做之旋轉限制被解除。 After the end of the wire W is bent to the side of the steel bar S, the motor 80 is driven in the forward rotation direction, whereby the motor 80 moves the movable member 83 in the direction of arrow F, which is the forward direction. The movable member 83 moves to the predetermined position in the arrow F direction, whereby the movable member 83 is drawn out from the locking of the rotation restricting member 84, and the rotation restriction of the movable member 83 by the rotation restricting member 84 is released.

藉此，馬達80更往正轉方向被驅動，藉此，握持線材W之握持部70係與彎曲部71一體旋轉，如第11(d)圖所示，扭轉線材W。 As a result, the motor 80 is further driven in the forward rotation direction, whereby the holding portion 70 holding the wire W rotates integrally with the bending portion 71, and the wire W is twisted as shown in FIG. 11(d).

在扭轉線材W後，馬達80往逆轉方向被驅動，藉此，馬達80使可動構件83往箭頭R所示之後方向移動。亦即，可動構件83係與馬達80之旋轉連動之旋轉動作，被旋轉限制構件84限制，而馬達80之旋轉被轉換成直線移動。 After the wire W is twisted, the motor 80 is driven in the reverse direction, whereby the motor 80 moves the movable member 83 in the backward direction indicated by the arrow R. That is, the movable member 83 is a rotating motion linked with the rotation of the motor 80, and is restricted by the rotation restricting member 84, and the rotation of the motor 80 is converted into linear movement.

藉此，可動構件83係往後方向移動。與可動構件83往後方向移動之動作連動，而往第1可動握持構件70L與第2可動握持構件70R自固定握持構件70C離開之方向位移，握持部70放開線材W。 Thereby, the movable member 83 moves in the backward direction. In conjunction with the movement of the movable member 83 in the backward direction, the first movable holding member 70L and the second movable holding member 70R are displaced in the direction away from the fixed holding member 70C, and the holding portion 70 releases the wire W.

第12圖~第13圖係詳細表示切斷線材之動作之動作說明圖，接著，說明以上述切斷部6A切斷線材W之動作之詳細。 Figures 12 to 13 are operation explanatory diagrams showing in detail the operation of cutting the wire rod. Next, the details of the operation of cutting the wire rod W by the cutting portion 6A will be described.

切斷部6A係可動構件83之動作，藉傳遞構件630 而被傳遞到傳遞機構62A的第1連桿620A，傳遞構件630往箭頭F方向移動，藉此，第1連桿620A的被按壓部623A被按壓，第1連桿620A係將軸622A當作支點而往箭頭C11方向旋轉。 The cutting portion 6A is the movement of the movable member 83, by means of the transmission member 630 The first link 620A transmitted to the transmission mechanism 62A moves the transmission member 630 in the direction of arrow F, whereby the pressed portion 623A of the first link 620A is pressed, and the first link 620A regards the shaft 622A as The fulcrum rotates in the direction of arrow C11.

切斷部6A係第1連桿620A之將軸622A當作支點之旋轉動作，藉第2連桿621A而被傳遞到可動刃部61A，可動刃部61A係將固定刃部60A當作支點而往箭頭C1方向旋轉。 The cutting portion 6A is a rotation action of the first link 620A using the shaft 622A as a fulcrum, and is transmitted to the movable blade 61A via the second link 621A. The movable blade 61A uses the fixed blade 60A as a fulcrum. Rotate in the direction of arrow C1.

當可動刃部61A往箭頭C1旋轉時，通過固定刃部60A開口601A之線材W，係藉可動刃613A而被壓抵到開口601A的開口端。並列之兩條線材W之中，一者之線材W係進入固定刃部60A的逃逸部602A1。藉此，如第13(a)圖所示，藉可動刃613A之動作而先行開始切斷被壓抵到固定刃部60A端緣部601A1之另一者線材W。 When the movable blade 61A rotates toward the arrow C1, the wire W passing through the opening 601A of the fixed blade 60A is pressed against the opening end of the opening 601A by the movable blade 613A. Among the two parallel wires W, one wire W enters the escape portion 602A 1 of the fixed blade portion 60A. As a result, as shown in FIG. 13(a), the movable blade 613A operates to start cutting the other wire W which is pressed against the end edge 601A 1 of the fixed blade 60A.

在開始切斷另一者之線材W後，當此另一者之線材W被切斷至既定位置時，將一者之線材W藉可動刃613A之動作，壓抵到固定刃部60A逃逸部602A1的端緣部。藉此，如第13(b)圖所示，開始切斷一者之線材W。在本例中，逃逸部6O2A1之形狀係被設定，使得在開始切斷另一者之線材W後，當此另一者之線材W被切斷徑向之一半以上時，開始切斷一者之線材W。亦即，自開口601A至逃逸部602A1端緣部為止之距離，係被設定成約為線材W直徑之一半。 After starting to cut the wire W of the other, when the wire W of the other is cut to a predetermined position, the wire W of one is pressed against the escape portion of the fixed blade 60A by the action of the movable blade 613A The edge of 602A 1 . As a result, as shown in Fig. 13(b), one of the wires W is started to be cut. In this example, the shape of the escape portion 6O2A 1 is set so that after the wire W of the other is cut, when the wire W of the other is cut by more than half of the radial direction, the cut is started. The wire W. That is, the distance from the opening 601A to the edge of the escape portion 602A 1 is set to be about half of the diameter of the wire W.

如第12(a)圖所示，當可動刃部61A更往箭頭C1旋轉時，如第13(c)圖所示，已經先行開始切斷之另一者 之線材W之切斷結束。而且，如第12(b)圖所示，當可動刃部61A更往箭頭C1旋轉時，如第13(d)圖所示，延遲開始切斷之一者之線材W之切斷結束。 As shown in Fig. 12(a), when the movable blade portion 61A rotates further toward arrow C1, as shown in Fig. 13(c), the other one has already started cutting The cutting of the wire W ends. Furthermore, as shown in FIG. 12(b), when the movable blade portion 61A rotates further toward the arrow C1, as shown in FIG. 13(d), the cutting of the wire W, which is one of the delayed cuttings, ends.

在切斷剖面形狀呈圓形之線材W之動作中，在刃部到達直徑之位置附近時，負載變得最高。在此，藉切斷並列之兩條線材W之構造，於開始切斷線材W之時間點設置差值。首先，在開始切斷第1條線材W後，當此線材W被切斷至徑向之一半以上之位置時，開始切斷第2條線材W。 In the operation of cutting the wire W having a circular cross-sectional shape, the load becomes the highest when the blade reaches the position near the diameter. Here, by cutting the structure of two parallel wires W, the difference is set at the time when the wire W starts to be cut. First, after starting to cut the first wire W, when the wire W is cut to a position above one-half in the radial direction, the second wire W is started to be cut.

比較切斷並列之兩條線材W之情形時，切斷一條線材W者係負載較少。藉此，首先，先行開始切斷一條線材W，藉此，負載被減少。又，第1條線材W被切斷至徑向之一半以上之位置時，通過負載成為最大之位置，所以，開始切斷第2條線材W，藉此，即使切斷兩條線材W，也可減少負載。而且，在結束切斷第1條線材W之前，開始切斷第2條線材W，藉此，可抑制切斷所需要時間之增加。 Comparing the case of cutting two parallel wires W, the load is less when one wire W is cut. In this way, firstly, the cutting of one wire W is started, whereby the load is reduced. Also, when the first wire W is cut to a position more than one-half of the radial direction, the passing load becomes the largest position. Therefore, the second wire W is started to be cut. Thereby, even if the two wires W are cut, Can reduce the load. In addition, before the cutting of the first wire W is finished, the cutting of the second wire W is started, thereby suppressing an increase in the time required for cutting.

如上所述，可謀求減少兩條線材W切斷時之負載，所以，藉鋼筋捆束機1A的各馬達之小型化、及機構部位之小型化，本體部整體可小型化。又，藉馬達之小型化、及負載之減少，可減少消耗電力。 As described above, it is possible to reduce the load when the two wires W are cut. Therefore, the size of each motor of the reinforcing bar binding machine 1A and the size of the mechanism can be reduced to reduce the size of the entire main body. In addition, the miniaturization of the motor and the reduction of the load can reduce the power consumption.
